Specification of Letters Patent.

Application filed April 6, 191-2. Serial No. 829,822.

T 0 (Illa/17mm it may concern Be it known that I, THEODORE Mn'rznnnn,

a citizen of the United States of America,

and a resident of the borough of Brooklyn, county of Kings, city of New York, State of New York, have invented certain new and useful Improvements in 'lalking-Machines, of which the to owing is a specification.

This lIlVQHLlOIl relates to talking machinesand has as its objects the production of such machines in a simple, compact and portable forin the production of such machines which may be used without an amplifying born but will still give an amplified sound in a manner pleasing to the ear, together with means for intermittently damping the sound so as to produce the effectpf a swell in tone. 1 accomplish these objects by extremely simple and inexpensive means together with other objects as will hereinafter appear.

The preferred form of device is so constructed as to simulate adresssuit case, with a smooth, unbroken outer surface, without unseemly or conspicuous projections or projecting apparatus of any kind extending through any portion of it. To arrange the talking machine apparatus and the necessary records, preferably in disk form, within also one of the objects of my invention.

In the following I have described, in con nection with the accompanying drawings, the preferred form of my invention, the features thereof being more particularly set forth hereinafter in the claims.

In the drawings Figure l is a perspective view of one form of my talking machine, with the casing open and the parts assembled ready for the closing of the casing and for transportation; Fig. 2 is a detail of one portion of the casing on the broken line 22 of Fig. 1, showing a means for supporting th reproducer arm, when not in use, in the cover or lid of. the casing; Fig. 3 is a sectional view, parts being broken away, on theline 3-3 of Fig. 1, showing the relation of the disk records to the covcrof the casing and the cushioning belt holding the records in place and preventing them from being damaged by the other parts of the machine; Fig. 4 is a perspective View of the casing closed; and Fig. 5 is 3 front elevatipn showing" the talking machine proper in operative position, the resonance chamber or sound amplifying box being shown in transverse vertical section.

Similar numerals of reference indicate similar parts throughout.the several views.

As shown in'the drawingsthe casing coniprises two portions, 10 and 11,, portion 10 being adapted to contain the talking machine apparatus proper, as hereinafter referred to, and portion 11 being adapted to contain the disk recordsand reproducer arm when not inuse, and to act as a cover to the Ratented May 4, 1915.

portion 10. Portions 10 and 11 are shown as hinged together by hinges 1Q, 12, and provided respectively with a hasp or lock 13 for securing the two portions together when -in closed position, and with a handle ll for the ready carrying of the apparatus. 15 indicates a disk support mounted to ro tate on motor shaft 16 in the usual manner, the shaft 16 being driven by any suitable motor mechanism (not shown) housed in portion 10 of the casing beneath disk support 15.

17 indicates a suitable brake device for controlling the starting and stopping of disk support 15 and 18a suitable regulating device for the motor. These features constitute no part of my invention and may be of any well-known and suitable construction.

19 indicates the resonance chamber or sound amplifying box arranged at one end of portion 10. The walls of chamber 19 are of a suitable resonant material, such as wood, and the chamber is preferably V shaped in cross section as shown in Fig. 5,

the ends of the chamber being sloped or beveled from the top'toward the bottom thereof as shown in Fig. l, the chamber, as shown, being thus in the form ofa triangu- .lar prism extending across the end of portion 10 with theend w'allsof the chamber flaring outwardly and upwardly.

The rcproducer 21, as well as the rcproducer arm 22, may be of any ordinary and well known type and construction.

23 indicates a collar at the end of the reproducer arm adapted to have pivotal con' nection with said arm and to bc fitted downwardly within socket piece "24 carried by bridge 25 extending across the middle portion of resonance chamber 19.. The bridge 25 is preferably made of wood and is provided with an aperture 25' registering with the opening in socket piece 24. The sound waves from the reproducer are thus conv veyed by the reproducer arm through socket piece 24 and aperture. 25 into resonance chamber 19 whence the sound waves emerge a strap 26.

throu h the spaces at either side of bridge 25, he form oi resonance chamber described has proved to give a very clear, sweet and loud amplification of the sound Waves coming from the reproducer and Jithout the necessity of using an amplifyxig born, or other sound conveying conduit.

As the machine is especially designed-for ready portability incomplete form ready for use at picnics or other transient entertainments, the casing is adapted to provide means for accommodating a considerable number of records, the whole device being a complete single, unitary or self contained apparatus.- The records are indicated by R and are shown as housed within portion or coder 11 of the casing, and held in place by As shown, I have employed a strap having its outer ends attached to cover 11 at points 2? and 28, the inner ends being adjustably connected by buckle 29. The sizes of the casings ma be varied to accommodate records of di crent diameters, the casing being preferably so constructed that the disks are in tangential contact with the opposite inner walls and one end of the same.

The strap 26 holds the disks in place on the free'side and forms a cushion for the disks against the end wall of the casing. Strap 26 moreover prevents the records from contacting with the socket iece 2% or shaft 16 should'they project so ciently into the cover when the casing is closed, both the strap and the socket and 4 shaft being preferably so alined as to be superposed when the casing is closed. For this reason the strap is preferably made of fabric or other soft flexible material which will not damage or abrade the records and constitutes, in effect, a cushioning device preventing the records from coming into any damaging or abrading contact with any other part of the device, especially while undergoing transportation.

When disassembled and the casing is ready to be closed the reproducer and its arm are supported in cover 11, by frictional contact between sleeve 23 and socket piece 24, as Well as by being seated in recessed block 30 secured at one end of the cover. Block 30 is also. rovidcd with a notch or recess 30 at the ottom into or through which the shank of winding crank 31 is slipped to hold the same securely in position.

32, 32, indicate dampers or sound deadeners hinged or otherwise secured at one side of the openings into resonance chamber. 19 and at either side of bridge 25. The deadencrs 32 may be felt covered to fit more or less tightly into said openings, the hinges 33, being adapted to hold them in any do sired position or to permit them to be swung entirelv awa from saido enin 3 more or less closing and opening either one or both of said deadeners the'sound issuing from the resonance box can be produced with more or less swell as desired or the full I effect of the amplified sound from the resonance chamber can beobtained by leaving the openings thereto entirely free either by folding back said deadeners or by removing them altogether.

it is obvious that many of the details of:
